INDEX. 



Names, as ' Acrasieae,' ' Abrothallus,' ' Achlya Braunii,' with no further addition, refer to the 

 course of development of the Orders, Genera, &c., as described in the second division of the first 

 part and in the second and third parts ; those which are followed by some additional word, as 

 ' Achlya apiculata, capacity of germination,' refer to the remaining sections of the book. An 

 asterisk after the number of a page indicates a Figure.
